My concern tracks that same assumption and makes it more concrete: the paper itself acknowledges that laboratory-specific tacit knowledge is scarce and largely undocumented, and it offers no evidence that the proposed remedies work for materials experiments. This is genuinely the most load-bearing uncertainty for the central claim. However, the paper is explicitly a perspective and roadmap, not an empirical demonstration. It repeatedly hedges the central claim, acknowledges current limitations in hardware precision, model reliability, and data availability, and calls for benchmarks and datasets as next steps. Given that framing, the absence of direct evidence does not invalidate the paper's contribution; it identifies where future validation is needed. Therefore the reader's ACCEPT verdict remains appropriate, and I would not adjust it. The concrete benchmark proposed would test the assumption directly, but until such evidence exists, the paper's cautious, forward-looking presentation justifies acceptance as a perspective piece.","tokens_in":16674,"tokens_out":4042,"duration_ms":52231,"concrete_test":"Run a controlled benchmark on one representative materials-lab task requiring tacit knowledge, for example powder weighing and transfer under inert atmosphere.

For this to hold, the data bottleneck identified in Section 3.3 must be resolved: transformers require hundreds of times more data than humans for knowledge retention [68], and Section 3.4 concedes that laboratory-specific tacit knowledge (glassware specifications, nuanced techniques, undocumented procedures) is largely absent from web-scale training data. The proposed remedies are synthetic data augmentation and external cognitive systems (Science Exocortex), but these are presented as research directions, not demonstrated capabilities. Synthetic data generated by models that already lack the target knowledge can propagate or amplify errors, and external cognitive systems still depend on human experts to supply the missing knowledge, which partially undercuts the 'without standardization' vision. No benchmark or experimental result in the paper shows that current or near-term foundation models can acquire and reliably use lab-specific physical knowledge at the precision and safety levels required for autonomous materials experiments. The central claim is therefore an extrapolation from cooking, manipulation, and programming-agent successes, not from evidence in materials laboratories.","agreement_with_reader":"agree"},"referee_report":{"model":"deepseek-v4-flash","summary":"This perspective argues that foundation models—large language models, multimodal models, and robotic foundation models—are the key enabling technology for flexible laboratory automation in materials research, allowing open-ended experiments without full hardware standardization.

The paper is a valuable synthesis for a broad community: it gathers scattered literature from robotics, AI, chemistry, and materials science, and it is notably honest about the limits of current evidence—for example, the glassware misidentification is explicitly presented as a single anecdote, and the data-efficiency limitation of transformers is acknowledged with reference to scaling-law studies. The roadmap is falsifiable in principle, and the explicit calls for laboratory-specific benchmarks, datasets, and human-AI integration are concrete and actionable. The main weakness is that the central claim rests on extrapolation from non-laboratory domains, which the authors themselves partially concede.","major_comments":[{"comment":"Section 3.1 asserts that 'the key technology for flexible adaptation to various sample types, devices, communication standards, and databases lies in highly versatile AI agents and foundation models for robots,' yet the supporting evidence in Sections 3.2-3.4 is drawn almost entirely from programming, web-based agents, cooking, and tabletop manipulation. The manuscript itself notes in Section 3.4 that ChatGPT misidentifies a common piece of laboratory glassware and that lab-specific tacit knowledge (size specifications, nuanced techniques, undocumented procedures) is largely missing from web-scale training data. Because this assertion is the central thesis, it should be explicitly framed as a research hypothesis rather than an established fact, with a falsifiable validation path (e.g., quantitative benchmarks on lab-specific perception, planning, and manipulation tasks) and a discussion of what evidence would strengthen or weaken the claim. Without this framing, the roadmap risks being read as an extrapolation from adjacent domains rather than a grounded assessment.","section":"Section 3.1, Section 3.4"},{"comment":"The proposal to overcome transformer data inefficiency using synthetic data augmentation is not supported by a discussion of a critical circularity risk: if synthetic data are generated by the same foundation models that lack the target tacit knowledge, the augmentation may propagate or amplify existing errors. The paper states that 'a naive approach of merely training models on scientific data may not effectively capture user-expected information' and then suggests expanding methodologies with synthetic data, but it does not specify a source of synthetic data that is independent of the deficient model (e.g., physics-based simulators with ground-truth state or expert-curated data). Adding a concrete discussion of how the synthetic data would be generated, validated, and shown to improve real-world lab performance would make the roadmap more credible.","section":"Section 3.3"}],"minor_comments":[{"comment":"Reference [52] cites arXiv:2501.05789, which is the same identifier as reference [49]; the intended arXiv number for the survey on large language model based agents should be corrected.","section":"References"},{"comment":"The DOI for reference [85] is malformed ('10.1146/((please'), likely a placeholder artifact; it should be completed or removed.","section":"Reference [85]"},{"comment":"The caption says 'using an Unrealistic engine,' which should read 'using the Unreal Engine.'","section":"Figure 5 caption"},{"comment":"In the description of RoboCat, 'from as few as around 100 demonstrations' is slightly vague; a precise number or range would be clearer, though this is a minor issue.","section":"Section 4.2"}],"recommendation":"minor_revision","confidential_remarks":"The paper is a well-structured perspective that does not overclaim its evidence base: the glassware example is clearly anecdotal, and the limitations of current models are acknowledged.

If you need a current map of where foundation models, robot control, and laboratory automation intersect, with a sensible two-axis roadmap, this is a good one to point people to. The authors know the literature, cite the right recent work, and are unusually honest about what is still missing.\n\nWhat is actually new: very little. A single GPT-4.5 glassware misidentification (Fig. 4) is illustrative, not a measurement. The synthesis of cooking robotics with lab automation, and the distinction between cognitive and physical roles, are useful organizing frames. The roadmap is not a bold new agenda but a balanced consolidation. That is enough for a perspective.\n\nSoft spots: the central claim in Sec. 3.1—that versatile AI agents and robot foundation models are the key to lab automation without full standardization—is an extrapolation from cooking, tabletop manipulation, and programming-agent successes to materials laboratories. The stress-test note is right that the data bottleneck in Sec. 3.3 is not solved: lab-specific tacit knowledge is largely absent from web-scale data, and synthetic data augmentation and the Science Exocortex are research directions, not demonstrated capabilities. But the paper deserves credit for saying this itself. It does not pretend the problem is solved; it flags these as open challenges. So the concern is a caveat about a perspective judgment, not a fatal flaw. Also, the phrase 'practical accuracy comparable to humans' for versatile AI agents in Sec. 3.1 is stronger than current evidence supports. Minor: ref. [52] has a duplicated/incorrect arXiv number (it matches ref. [49]).\n\nThe citation pattern is fine. There are several self-citations, but they are on-topic and none looks like padding.\n\nBottom line: this paper is for newcomers, funders, and anyone writing an introduction to AI-driven lab automation. It will not change your research agenda, but it will save you time and give you a fair set of references. I would send it to peer review; I probably will not cite it in my own work.","headline":"A useful, well-hedged perspective on foundation models for lab automation that earns its place as an overview; the central 'key technology' claim is a considered prediction, not a proven result, and the paper mostly says so itself.","tokens_in":17392,"tokens_out":2539,"would_cite":false,"duration_ms":33216,"reading_group":"maybe","serious_thinker":"yes","would_accept_peer_review":true},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"deepseek-v4-flash","headline":"This perspective argues that foundation models—versatile AI agents and robotic foundation models—are the key technology for flexible laboratory automation, able to adapt to diverse samples, devices, and data formats without full…","keywords":["laboratory automation","foundation models","large language models","robotics","materials science","AI agents","self-driving laboratories"],"falsifier":"Run the current best LLM-based lab agents on a held-out set of real laboratory protocols described only in single experimental notes, with no additional training, and compare their success rate against simple rule-based automation.

The paper identifies highly versatile AI agents and robotic foundation models as the key technology for adapting to varied sample types, devices, communication standards, and databases, and lays out a roadmap based on these dual roles. It acknowledges serious limits, especially the transformer architecture's data hunger and the gap between web-trained knowledge and real lab practice, and argues these can be addressed through synthetic data, benchmarks, and external cognitive systems.

The argument's internal mechanism is that general-purpose pretrained models transfer knowledge across tasks via zero-shot learning, replacing task-specific, rule-based control, while the limiting mechanism is the transformer scaling law, which requires far more data than a single experiment or lab note provides.","core_discovery":"The central claim is that foundation models, rather than modular hardware standards, are the pivotal enabling technology for flexible laboratory automation. The paper proposes that AI agents and robot foundation models can act as a 'brain' that plans experiments and interprets data and a 'body' that physically operates equipment, allowing robots to work in open-ended lab environments without uniform modularization of instruments. Even before humanoid robots mature, foundation models can automate the standardization of data from analytical instruments and coordinate specialized modules.
